Updated: In an exclusive, Christine Pelisek of the Daily Beast has the names and photos of the new victims connected to the investigation -- here. We also update after the jump with some of the names police have subsequently put forward.

Six of the new possible cases, all women, are missing persons; one involves an unsolved murder; the last is an unidentified woman, police said. Four of the cases are completely new connections to the "Grim Sleeper," cops allege.

In July Lonnie Franklin Jr., 57, was arrested at his South L.A. home and subsequently charged with the killing spree that involved 10 mostly area women whose bodies were often found in alleys around his home.

In December detectives released 180 photos of women they said they found in Franklin's home. They wanted to determine if any were missing people who might be tied to the Grim Sleeper case.

The possibly new cases include missing-woman reports from as far back as 1982 and from as recently as 2006, police said.

Photographs of the six missing women were set to be displayed at the news conference.

One of the eight involves the 1988 unsolved murder of Inez Warren.

The serial killer case got its "Grim Sleeper" title from the LA Weekly's coverage: Reporter Christine Pelisek discovered that a serial murderer was on the loose in South Los Angeles, and that a wide gap in killings in the 1990s existed (thus the "sleeper" aspect).

Update: IDs of two of the missing women, Ayellah Marshall and Rolenia Morris, were found at Franklin's home, police said. The photograph of the unidentified woman was also found there, they said.

The stash Franklin kept in a refrigerator in his garage also included a photo of one of the 10 victims included in the case against him, police said.

The other missing women possibly linked to the case were identified by cops as Cathern Davis, Rosalind Giles, Lisa Knox and Anita Parker. They were said to have similar "lifestyles" as those of other Sleeper victims.

Lead Detective Dennis Kilcoyne told reporters new charges wouldn't happen anytime soon, but that they weren't out of the question.

For now cops want anyone with information about the missing women to call them at 877-LAPD-24-7.
